V0.22 - Minor update

I'm adressing some of the issues you have been reporting to me:

[h3]Quality of life / UX[/h3]

• Tech tree open after prestige
  
• Tutorial font size increased
  
• Some popup font size increased
  
• WIP popup no longer in front of main menu
  
• Feedback request happens only after coming back twice from a run
  

[h3]Gameplay[/h3]

• Poop treshold to level up a tree slightly changed:
  BEFORE: 2 - 16 - 128 - 1,024 - 8,192‬
  NOW: 5 - 30 - 180 - 1080 - 6,480
  This should slighlty improve the feeling of progression by reducing the massive snowball early game
  but also making late game less daunting.
  
• Increased max manual click power multiplier from x3 to x4.
  

Don't hesitate to give me your thoughts about the changes !
